Objective:To study the role of endoplasmic reticulum stress(ERS)on ecdysterone(EDS)influenced protective effect in H2O2induced myocardial injury.Methods: The H9c2 cells were randomly divided into control group(normal cells),H2O2 groups(the cells treated with H2O2at concentrations of 1×10-3,1×10-4,1×10-5mol/L,respectively);EDS group(the cells were exposed to H2O2and treated with EDS at concentrations of 25,50,100 μmol/L respectively).The cell activity and apoptosis were measured by MTT assay and flow cytometry,respectively.The protein levels of Bcl-2,Bax,cleaved-caspase-3,caspase-4,caspase-7, caspase-12,GRP78 and CHOP were deter mined by Western blot.The MDA content and SOD activity were detected by the MDA and SOD detection kits.Results:The cell activity was decreased,cell apoptosis was increased,the content of MDA was elevated,the activity of SOD was inhibited and the protein expression of GRP78 and CHOP were increased in H2O2group as compared with control group, which were all significantly reversed by EDS treatment(P<0.05).Conclusion: Ecdysterone exhibits a protective effect on the cardiomyocytes with H2O2induced injury by inhibiting endoplasmic reticulum stress.

OBJECTIVETo determine human epidermal growth factor receptor 2 (HER2) status in breast carcinoma by the techniques of a fully automated immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), to compare the concordance of protein expression with gene amplification and to explore the optimization in process quality control.

METHODSA prospective study of invasive breast cancer specimens excised between May 2009 and April 2011 at the Cancer Hospital, Chinese Academy of Medical Sciences was conducted by automated IHC staining with the new 4B5 rabbit monoclonal antibody and FISH. An evaluation was performed according to the ASCO/CAP guidelines (2007) and Chinese guidelines (2009). The gene amplification status of 740 cases were detected by FISH.

RESULTSA total of 2420 cases of breast invasive ductal carcinoma without pre-operation therapy were tested by automated IHC. 551 cases (22.8%) were scored as positive (3+), 664 cases (27.4%) as equivocal (2+), and 1205 cases (49.8%) as negative (1+/0). Gene amplification was detected in 98.0% (242/247) HER2 protein expression positive (3+) cases and in 13.6% (53/389) equivocal (2+) cases. One of 247 (0.4%) HER2 expression 3+ cases and 5 of 389 (1.3%) HER2 expression 2+ cases were equivocal for gene amplification. No gene amplification was detected in expression negative (1+/0) cases by FISH (0/104). The overall concordance between IHC and FISH was 98.6% [(242 + 104)/(247 + 104)].

CONCLUSIONSThere is a high concordance rate between automated IHC with 4B5 rabbit monoclonal antibody and FISH results for assessing the HER2 gene amplification status in surgically-excised breast cancer specimens, suggesting that automated IHC with 4B5 antibody can provide a reliable method to detect HER2 overexpression for eligibility of HER2 targeted therapy.

OBJECTIVEThe aim of this study was to observe the association between the occurrence of esophageal cancer lesions and esophageal mucosa fold (white ridges), and further identify where is the initial origin of esophageal cancer lesions in the esophagus mucosa.

METHODSThis was a cohort study which recruited 551 subjects underwent endoscopic examination in a high risk area of esophageal cancer in Linxian, Henan Province in 1987. 339 subjects with esophageal white ridges, and with red area or erosion lesion at the surface of the white ridges, was studied as exposure group. Other 212 subjects whose esophagus had no white ridges and pathological diagnosis was negative, was studied as control group. The endpoint was occurrence of pathologically confirmed esophageal cancer. After a 15-year follow-up, the results were compared between two groups.

RESULTSAmong the 551 subjects, there were 339 cases with esophageal mucosal white ridges in the exposure group. During the period of 15 year follow-up, the incidence of esophageal cancer was 11.8% (9/76) in 76 case with simple mucosal white ridges, 33.5% (88/263) in 263 subjects with white ridges and red area, or erosions on the surface of white ridge. While only 8.0% of subjects (17/212) developed esophageal cancer after the 15-year follow up in the control group. There was a significant difference between the two groups (P < 0.001).

CONCLUSIONEsophageal mucosal white ridge, especially white ridge with red area or erosions is closely associated with subsequent esophageal cancer occurrence in the esophageal cancer high risk area in China. It is suggested that esophageal mucosa with white ridge may be the initial origin of esophageal cancer. Further investigations focused on this spot are required.

OBJECTIVETo study the effect of Shenfu Injection (SF) on the apoptosis of prostate cancer PC-3 cells and its possible mechanism.

METHODSWe divided prostate cancer PC-3 cells into a blank control group and three experimental groups, the latter treated with SF at 50, 100, and 200 microl/ml, respectively, for 24, 48, and 72 hours. Then we determined the proliferation of the cells by MTT assay, measured their apoptosis by Annexin V/PI flow cytometry, and detected the expression of P53 mRNA by RT-qPCR.

RESULTSCompared with the blank control group, the survival rates of the prostate cancer PC-3 cells in the 50, 100, and 200 microl/ml SF groups were (93.76 +/- 2.63)%, (81.21 +/- 1.80)% and (18.01 +/- 3.84)% at 24 hours, (94.67 +/-1.11)%, (78.33 +/- 2.89)% and (10.34 +/- 1.44)% at48 hours, and (91.30 +/- 0.47)%, (36.67 +/- 1.56)% and (1.33 +/- 0.32)% at 72 hours, all significantly increased in a dose- and time-dependent manner (P < 0.05). The expression of p53 mRNA was also markedly increased in all the three experimental groups at 48 hours (P < 0. 05).

CONCLUSIONSF can inhibit the proliferation and induce the apoptosis of PC-3 cells, which may due to its upregulation of the p53 mRNA expression.

OBJECTIVETo investigate the operative reduction techniques and clinical results of surgical treatment of type C1 (AO/ASIF) acetabular fracture by posteroproximal-posteroanterior sequential reduction and internal fixation.

METHODSFrom August 2004 to January 2012, 13 patients with type C1 (AO/ASIF) acetabular fracture were treated by posteroproximal-posteroanterior sequential reduction and internal fixation. Of them, 8 cases were male and 5 cases were female with an average age of 42 years years old (ranged, 18 to 64). Pelvis 3-dimentional CT reconstruction were used to confirmed the classification of fracture, and the operation were performed during from 5 to 20 days with an average of 9.5 days. Operation time, blood loss, complications and reduction were recorded and evaluated. The function of hip joint were accessed at the final follow-up.

RESULTSThe operation time ranged from 190 to 290 min with an average of 240 min. The mean blood loss was 1 800 ml (ranged, 1 300 to 3 000 ml). One case had superficial infection and healed after 3 weeks. According to Matta reduction criteria, 8 cases obtained anatomical reduction, 4 cases got satisfied results and 1 cases got unsatisfied results. Eleven cases were followed up with an average of (24.0 +/- 8.0) months, and 2 cases were lost to follow-up. According to revised Mede d'Aubingne and Postel evaluation system, 7 cases got excellent results, 2 good, 1 moderate and 1 poor.

CONCLUSIONPosteroproximal-posteroanterior sequential reduction and internal fixation for the treatment of type C1 (AO/ASIF) acetabular fracture can achieve satisfied surgical proces and operation quality.

OBJECTIVETo investigate the related factors of portal vein tumor thrombosis (PVTT) in patients with HCC.

METHODSA total number of 234 patients with hepatocellular carcinoma (HCC) were included in this retrospective study. Uni-variate and multi-variate logistic regression analysis were employed to analyze the association between PVTT and 18 routine clinical parameters.

RESULTSAmong the 234 patients with HCC, 15% of patients (35/235) had PVTT. Univariate logistic regression analysis revealed significant association of age (P = 0.016), gamma glutamyl transferase (GGT, P = 0.003), number of segmental invasion (P = 0.007), microvascular invasion (P < 0.01), segment location of S2 (P = 0.001), S3 (P = 0.000), S4 (P = 0.004) and S6 (P = 0.016). Multivariate analysis shows potential significant predictors of PVTT in HCC were age (RR: 0.373; 95% CI: 0.146-0.954; P = 0.040), the tumor location of S3 (RR: 4.625; 95% CI: 1.916-11. 165;P = 0.001), GGT (RR: 4.091; 95% CI: 1.448-11.553; P = 0.008) and microvascular invasion (RR: 20.912; 95% CI: 4.745-92.172; P < 0.01).

CONCLUSIONSPVTT occurred more commonly in the younger (< 50 years old), and those with high level of GGT, segment location of S3 and microvascular invasion.

OBJECTIVETo evaluate the outcome of emergency adult right lobe living donor liver transplantation for fulminant hepatitis.

METHODSNine cases of adult right lobe living donor liver transplantation were performed from September 2002 to August 2005, the clinical and follow-up data was analyzed.

RESULTSAccording to Child Pugh Turcotte (CPT) classification, 9 patients were classified as grade C before transplant. The Model for End-Stage Liver Disease (MELD) scores of these patients were 26.7 +/- 8.8. The principal pre-transplant complications included hepatic encephalopathy (5 cases), electrolyte disturbance (3 cases), renal failure (2 cases), gastrointestinal bleeding (1 case). The operations in donors and recipients were all successful. The post-transplant complications induced pulmonary infection in 2 patients, acute renal failure in 3 and transplantation related encephalopathy in 1. There were no primary graft non-function and no blood vessel and bile tract complications occurred. One-year survival rate was 55.6%. No serious complication or death found in donors.

CONCLUSIONSEmergency adult to adult living donor liver transplantation is an effective treatment for fulminant hepatitis but the safety of the donors should be assessed strictly preoperation.
